From the replies I guess I'm not the only one!

I figured a good leather cleaner would do the trick but my main concern was the dye from the jeans would possibly transfer onto the leather permanently and wouldn't come off.

I'll purchase a good leather cleaner and give my seat a good clean tomorrow.

I guess the only option is to simply let the seat get stained and clean it often.....and no....not wearing jeans isn't an option since that's all I wear....7 days a week...365 days a year....or I could drive with my pants down but that's probably not a good idea! lol...
